Soy Milk is Healthy

There's nothing wrong with soy milk. The studies show that soy reduces the risk of prostate cancer in men, and in women it reduces the risk of breast cancer. The cancer risk reduction is caused by the phytoestrogens in soy. The scare that phytoestrogens feminize men is also overblown given that the affix "phyto-" means "plant" and plant estrogens have weak to no effect on humans. It is animal estrogen such as estradiol in dairy milk that has been shown to reduce testosterone levels in men, and there are many studies that suggest dairy milk may increase prostate cancer risk although this is not conclusive. Bottom line is if you're really concerned, just drink almond milk.
